Synchrony behind Apache 2.4 over SSL does not work?

Timothy Harris

I have new Confluence 6.0 installed behing apache 2.4.18 running over SSL. When collaborative editing is enabled I cannot edit pages. Just stays there loading. I have followed the instructions provided by atlassian as best I could. Can anyone see what I have done wrong?

The Apache config:

<VirtualHost *:443>
ServerName my.example.dk

ProxyRequests Off

<Proxy *>
Require all granted
</Proxy>

ProxyPass / http://localhost:8090/
ProxyPassReverse / http://localhost:8090/

SSLEngine On
SSLCertificateFile /etc/apache2/ssl/vhhr_signed_cert.crt
SSLCertificateKeyFile /etc/apache2/ssl/privateKey.key
#SSLCertificateChainFile /etc/apache2/ssl/int.cer

<Location />
Require all granted
</Location>

ProxyPass /synchrony http://localhost:8091/synchrony

<Location /synchrony>
Require all granted
RewriteEngine on
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
RewriteRule .* ws://localhost:8091%{REQUEST_URI} [P]
</Location>

</VirtualHost>

<VirtualHost *:80>
ServerName my.example.dk
Redirect Permanent / https://my.example.dk/
Redirect Permanent /synchrony https://my.example.dk/synchrony
</VirtualHost>

The server.xml file:

<Server port="8000" shutdown="SHUTDOWN" debug="0">
<Service name="Tomcat-Standalone">
<Connector port="8090" connectionTimeout="20000" redirectPort="8443"

<Engine name="Standalone" defaultHost="localhost" debug="0">

</Context>
</Host>

</Engine>

Note I have change the actual url to "my.example.dk"

Hi @Timothy Harris,

Could you check the following link first: https://confluence.atlassian.com/confkb/editor-does-not-load-in-confluence-6-x-due-to-could-not-initialize-class-org-xerial-snappy-snappy-859462192.html

I have a quick look through the httpd.conf settings and I would like you to suggest the following change for virtual host 443

<VirtualHost *:443>
ServerName my.example.dk
ProxyRequests Off
<Proxy *>
	Require all granted
</Proxy>

SSLEngine On
SSLCertificateFile /etc/apache2/ssl/vhhr_signed_cert.crt
SSLCertificateKeyFile /etc/apache2/ssl/privateKey.key
#SSLCertificateChainFile /etc/apache2/ssl/int.cer
 
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/synchrony
RewriteRule ^/(.*) http://my.example.dk:8090/$1 [P]

<Location />
	Require all granted
</Location>

ProxyPass /synchrony http://localhost:8091/synchrony


<Location /synchrony>
	Require all granted
	RewriteEngine on
	RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
	RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
	RewriteRule .* ws://localhost:8091%{REQUEST_URI} [P]
</Location>
</VirtualHost>
